CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of priority of Korean Patent Application No. 10-2013-0130599 filed on Oct. 30, 2013, the disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a storage rack that stores goods.

2. Description of the Related Art

In general, as cylindrical products having hollow portions, there are various products wound in a cylindrical shape such as steel plate coils, wire rods or bar in coil, tires, fibers, and newspapers.

Among the cylindrical products having hollow portions, the product required to be minutely handled may be the wire rod.

Since the wire rod is formed by winding a plurality of coils in a circular shape, the wire rod is lengthened due to its elasticity. Thus, there are many problems in that the product may be deformed or damaged due to contact between the product and equipment when the product is handled and the product may fall down and be dropped by being slanted due to rotational inertia when the products are moved in a motion line of distribution of the products.

FIG. 1 is a diagram showing a general system for storing wire rods.

As shown in FIG. 1, there is illustrated a typical type in which products 2 are delivered to be stored by a forklift or a C-shaped hook unit 1 attached to a trolley T suspended from a ceiling crane C traveling along both rails C/R provided on a lower side of a ceiling of an indoor warehouse of a product factory or a crane provided on an upper side of an outdoor warehouse in a yard flatland. This system is a storage structure in which the products come in direct contact with the bottom 3 of the warehouse in the flatland, and the wire rods in a cylindrical shape are layered within four to five stages in the form of zigzag.

Accordingly, in such a storing method, since the products 2 come in direct contact with the bottom 3 and are upwardly stored to be layered in four to five stages, there are a decrease in efficiency of storage space and limitations in storage capacity. Further, it is difficult to selectively stock or rotate the products. In addition, when the products are handled or delivered, manpower is largely required due to frequent operations of delivery equipment such as the forklift or the C-shaped hook unit 1 attached to the trolley T suspended from the ceiling crane C. There is a problem in that such a goods handling method is economically inefficient.

Moreover, the products may be scratched or damaged due to contact between the bottom 3 and the products 2, contact between the layered products 2, and frequent movements (deliver and shipment) of the goods. Especially when the products are stored in the outdoors, since the products are exposed to moisture, the products may be severely corroded.

As the related art for solving such problems, there is known Japanese Patent Publication No. 2000-109204.

As shown in FIG. 2, this technology discloses a multi-tier warehouse system for wire coils, and a multi-tier warehouse structure that stores products in multiple stages and is configured to automatically stock or rotate the products.

In this multi-tier warehouse, a pair of posts 4 is provided at a bottom 3 at a regular distance, and hangers 5 in a cantilever type are attached to protrude from the posts 4 at regular heights. Further, goods-falling prevention units 7 are provided at a stacker crane 6, and products 2 are delivered and transferred to hang the products to the hangers 5. Thus, there is a merit in that the products 2 in large quantities are automatically stored in the hangers 5 in multiple stages.

However, in this system according to the related art, in order to prevent the heavy products from being loosed and to provide stability of the structure, regular distances d1 and d2 are set between the pair of posts 4, and the goods are supported at two points where the hangers 5 are directly provided to the posts 4 at the regular heights of the pair of posts 4. In this structure, since an unnecessary space is set between the post frames, layering efficiency may be decreased, and the land may be more needed.

Accordingly, in order to solve the problems, the present applicant has invented a storage rack for cylindrical goods and filed Korean Patent Publication No. 10-2010-0095714. As shown in FIG. 3, in this storage rack, a goods storage unit is provided in a hanger type, goods supporting posts for supporting goods, and a lattice horizontal beam assembly that horizontally supports the goods supporting posts is integrally connected to a lattice post assembly. Further, the goods supporting posts are supported by a post supporting member provided within the lattice horizontal beam assembly, and while the lattice horizontal beam assembly withstands a horizontal load, the goods supporting posts withstand a vertical load. With such a configuration, it is possible to increase stability of the entire structure.

In the storage rack for cylindrical goods described in Korean Patent Publication No. 10-2010-0095714 which is previously filed by the present applicant, has the same purpose as that of the present invention, and is very similar to a structure of the present invention, the storage rack in which there is a large distance between the lattice posts is appropriately configured using horizontal support members having high strength. However, since a large horizontal support member occupies a goods layering space, the goods need to be layered at a position where the horizontal support member is not positioned. For this reason, since installation positions of goods hanging beams are not constant in a vertical direction, it may be highly likely to delay time in controlling the stock and rotation of the goods, and the height of the entire rack may increase.

Accordingly, the present applicant has invented a storage rack capable of being provided to constantly maintain a minimum distance between the goods in a vertical direction by substantially adjusting a size of the horizontal support beam to be suitable for a size of the goods supporting post and installing the horizontal support beam at the goods supporting post between the goods layering spaces so as not to allow the horizontal support beam to interfere in the goods layering spaces in the rack in which a distance between the lattice posts is narrow.

SUMMARY OF THE INVENTION

An object of the present invention provides a storage rack with which it is possible to increase space availability to increase storage efficiency and to provide structural stability by providing a storage rack capable of having a low rack height as a whole and constantly maintaining goods at a minimum distance in a vertical direction without interference by a horizontal support beam by fastening an end of a goods supporting post to a lower end of the horizontal support beam to be overlapped therewith.

An object of the present invention also provides a storage rack capable of being simply assembled during the installation by arranging a horizontal support beam of a single member between lattice posts.

According to an aspect of the present invention, there is provided a storage rack provided with a plurality of goods layering spaces to store goods. The storage rack includes: a plurality of lattice posts that includes first and second post elements arranged in a Y-axis direction at a first distance, and a plurality of vertical lattice members connecting the first and second post elements; a post connecting beam that connects the first and second post elements of each of the lattice posts; a horizontal support beam whose ends are fastened to centers of the post connecting beams to connect the lattice posts arranged in an X-axis direction at a second distance; a plurality of goods supporting posts whose ends are fastened along a central line of the horizontal support beam to be arranged between the lattice posts, which are arranged at the second distance, at a predetermined distance along the goods layering spaces; and a plurality of goods hanging beams whose ends are fastened to the goods supporting post to be arranged in a Z-axis direction at a third distance. The end of the goods supporting post is fastened to the horizontal support beam to be overlapped therewith on the plane.

The horizontal support beam connecting the lattice posts may be a single member.

The end of the horizontal support beam may be fastened to the post connecting beam at a position which is one half of the entire length between both ends of the post connecting beam.

A distance between the end of the horizontal support beam and the first post element may be equal to a distance between the end of the horizontal support beam and the second post element.

The end of the horizontal support beam may be fastened to a post located at the outermost edge from an end of the post connecting beam.

The end of the goods supporting post may be completely overlapped with the horizontal support beam in the Z-axis direction.

The goods supporting post and the horizontal support beam may be an H-shaped structural steel member that includes flanges and a web between the flanges, and a width of the web of the goods supporting post may be equal to a width of the web of the horizontal support beam.

A thickness of the flanges of the goods supporting post may be equal to a thickness of the flanges of the horizontal support beam.

The goods supporting post and the horizontal support beam may be an H-shaped structural steel member that includes flanges and a web between the flanges, and the flanges of the goods supporting post 40 may be joined to the flanges of the horizontal support beam.

Here, the steel plate of the horizontal support beam and the web of the goods supporting post may be provided with at least one fastening hole, and may be joined by a bolt penetrating through the fastening holes.

The goods supporting beam may be an H-shaped structural steel member that includes an upper flange, a lower flange, and a web between the upper and lower flanges, and edges of the upper flange of the goods supporting beam that come in contact with the goods may be curved surfaces.

The goods supporting beam may be an integral type that is fixed to the goods supporting post, or a detachable type that is detachably attached to the goods supporting post.

The detachable goods supporting beam may be attached to or detached from a support bracket joined to the goods supporting post by a bolt.

The storage rack may further include first and second vertical braces that connect the lattice posts arranged in the X-axis direction at the second distance while crossing each other in a diagonal direction. Ends of the first and second vertical braces may be fastened to the post connecting beam.

The storage rack may further include a goods-supporting-post connecting member that is disposed at a height where the first and second vertical braces cross each other to be parallel so as to the horizontal support beam in the X-axis direction, and is fastened to the plurality of goods supporting posts.

FIG. 4 is a perspective view showing a storage rack according to the present invention.

As shown in FIG. 4, a storage rack 100 may include at least one first storage rack 110 in which goods supporting beams 50 are disposed at both sides of goods supporting posts 40, and at least one second storage rack 120 in which goods supporting beams 50 are disposed at one sides of the goods supporting posts 40.

Here, the first storage rack 110 may be disposed in a central region of a multi-tier warehouse, and the second storage rack 120 may be an edge region of the multi-tier warehouse.

The storage rack 100 including the first and second storage racks 110 and 120 has a plurality of goods layering spaces to be able to store goods 80.

The storage rack 100 may includes a plurality of lattice posts 10, post connecting beams 20, horizontal support beams 30, the plurality of goods supporting posts 40, and the plurality of goods supporting beams 50.

Here, the plurality of lattice posts 10 may be arranged in an X-axis direction at a regular distance.

In this case, each of the lattice posts 10 may include first and second post elements 11 a and 11 b that are arranged in a Y-axis direction at a regular distance, and a plurality of vertical lattice members 12 that connects the first and second post elements 11 a and 11 b.

The post connecting beam 20 may connect the first and second post elements 11 of the lattice post 10.

The horizontal support beam 30 whose ends are fastened to the post connecting beams 20 may connect the lattice posts 10 that are arranged in the X-axis direction at the regular distance.

The plurality of goods supporting posts 40 whose ends are fastened to the horizontal support beam 30 may be arranged between the lattice posts 10, which are arranged at the regular distance, at a regular distance along the goods layering spaces.

Here, the ends of the goods supporting posts 40 may be fastened to the horizontal support beam 30 to be overlapped therewith.

The plurality of goods supporting beams 50 whose ends are fastened to the goods supporting posts 40 may be arranged in a Z-axis direction at a regular distance.

As stated above, in the present invention, by fastening the ends of the goods supporting posts 40 to the horizontal support beam 30 to be overlapped therewith, it is possible to increase space availability to increase storage efficiency. Further, it is possible to provide structural stability.

Further, in the present invention, by disposing one horizontal support beam 30 between the lattice posts 10, it is possible to simplify assembly during the installation, so that it is possible to reduce installing cost and to shorten a construction period.

FIG. 5 is a perspective view showing a basic structure of the storage rack according to the present invention, FIG. 6 is a plan view of FIG. 5, FIG. 7 is a side view of FIG. 5, and FIG. 9 is a front view of FIG. 5.

As shown in FIGS. 5 to 9, the storage rack 100 may include the plurality of lattice posts 10, the post connecting beams 20, the horizontal support beams 30, the plurality of goods supporting posts 40, and the plurality of goods supporting beams 50.

Here, the plurality of lattice posts 10 may be arranged in the X-axis direction at a second distance d2.

In this case, each of the lattice posts 10 may include the first and second post elements 11 a and 11 b, and the vertical lattice member 12.

The first and second post elements 11 a and 11 b may be arranged in the Y-axis direction at a first distance d1.

The vertical lattice member 12 may connect the first and second post elements 11 a and 11 b, and may be plural in number.

Here, the vertical lattice members 12 may be connected to each other in the form of zigzag in the Z-axis direction between the first and second post elements 11 a and 11 b.

In this case, an angle θ1 between the vertical lattice member 12 and the first or second post element 11 a or 11 b may be an acute angle.

The post connecting beam 20 may connect the first and second post elements 11 a and 11 b of the lattice post 10.

The horizontal support beam 30 whose ends are fastened to the post connecting beams 20 may connect the lattice posts 10 arranged at the second distance in the X-axis direction.

Here, as the horizontal support beam 30 connecting the lattice posts 10, a single member may be used.

The end of the horizontal support beam 30 may be fastened to the post connecting beam at a position of L1/2 which is one half of the total length L1 between the both ends of the post connecting beam 20.

That is, a distance d11 between the end of the horizontal support beam 30 and the first post element 11 a may be equal to a distance d12 between the end of the horizontal support beam 30 and the second post element 11 b.

As described above, in the at least one first storage rack 110 in which the goods supporting beams 50 are arranged on the both sides of the goods supporting post 40, the distance d11 between the end of the horizontal support beam 30 and the first post element 11 a may be equal to the distance d12 between the end of the horizontal support beam 30 and the second post element 11 b.

Here, the first storage rack 110 may be disposed in the central region of the multi-tier warehouse.

However, in the at least one second storage rack 120 in which the goods supporting beams 50 are arranged on the one side of the goods supporting post 40, the distance d11 between the end of the horizontal support beam 30 and the first post element 11 a may be different from the distance d12 between the end of the horizontal support beam 30 and the second post element 11 b.

Here, the second storage rack 120 may be disposed at the edge region of the multi-tier warehouse.

As one example, in the second storage rack 120, the end of the horizontal support beam 30 may be fastened to a post located on the outermost edge from the end of the post connecting beam 20.

The horizontal support beam 30 may be an H-shaped structural steel member having both flanges and a web between the flanges.

Here, an axial line of the web of the H-shaped structural steel member in the horizontal support member 30 is horizontally positioned, so that the horizontal support member can have large bending resistance to force exerted in a horizontal direction.

As mentioned above, when one horizontal support beam 30 is disposed between the lattice posts 10, the horizontal support beam 30 does not interfere in the goods layering spaces.

Accordingly, as a width of the horizontal support beam 30 on a plane decreases, it is possible to increase space efficiency.

When the width of the horizontal support beam 30 decreases, since stiffness of the steel member is weakened, it may be necessary to reduce a distance between the lattice posts 10. However, when a member having a wider flange width is used as the steel member of the horizontal support beam 30 to increase stiffness, it is possible to effectively secure goods layering spaces without reducing the distance between the lattice posts 10.

The plurality of goods supporting posts 40 whose ends are fastened to the horizontal support beam 30 may be arranged between the lattice posts 10, which are arranged at the second distance d2, along the goods layering spaces at a fourth distance d4.

Here, the end of the goods supporting post 40 may be fastened to the horizontal support beam 30 to be overlapped therewith on the plane.

For example, the goods supporting post 40 may be completely overlapped with the horizontal support beam 30 in the Z-axis direction.

However, in some cases, the end of the goods supporting post 40 may be partially overlapped with the horizontal support beam 30 in the Z-axis direction.

As mentioned above, since the end of the goods supporting post 40 is overlapped with the horizontal support beam 30 on the plane, it is possible to increase structural stability and availability of the goods layering spaces.

The goods supporting post 40 and the horizontal support beam 30 may be an H-shaped structural steel member that includes flanges and a web between the flanges.

Here, a width of the web of the goods supporting post 40 may be equal to a width of the web of the horizontal support beam 30.

When the width of the web of the goods supporting post 40 is greater than the width of the web of the horizontal support beam 30, the goods layering spaces may be reduced. Accordingly, by using the members formed such that the width of the web of the goods supporting post 40 is substantially equal to the width of the web of the horizontal support beam 30, the flanges of the goods supporting post 40 come in contact with the flanges of the horizontal support beam 30, so that it is possible to ideally join the goods supporting post and the horizontal support beam as an integral structure.

Furthermore, a thickness of the flange of the goods supporting post 40 may be equal to a thickness of the flange of the horizontal support beam 30.

The flange of the goods supporting post 40 and the flange of the horizontal support beam 30 may be joined to each other.

As one example, the flange of the goods supporting post 40 and the flange of the horizontal support beam 30 may be joined through welding, but the present invention is not limited thereto.

The horizontal support beam 30 may include a steel plate that protrudes from the web of the horizontal support beam 30 toward the goods supporting post 40.

Here, the steel plate of the horizontal support beam 30 may be joined to the web of the goods supporting post 40.

As one example, the steel plate of the horizontal support beam 30 and the web of the goods supporting post 40 are provided with at least one fastening hole, and may be joined using a bolt penetrating through the fastening holes.

However, in some cases, the number of the steel plates of the horizontal support beam 30 may be different from the number of the goods supporting post 40 fastened to the horizontal support beam 30.

The plurality of goods supporting beams 50 whose ends are fastened to the goods supporting post 40 may be arranged in the Z-axis direction at a third distance.

Here, the goods supporting beams 50 may be supported by the goods supporting post 40 between the horizontal support beams 30, may be arranged up and down, and may be provided to protrude toward a path in the Y-axis direction.

The goods supporting beam 50 is a cantilever structure member that hangs and supports the goods.

The goods supporting beam 50 may be an H-shaped structural steel member that includes an upper flange, a lower flange, and a web between the upper flange and the lower flange.

A portion of the upper flange of the goods supporting beam 50 that comes in contact with the goods may have a curved surface.

That is, in the goods supporting beam 50, an axial line of the web of the H-shaped structural steel member is vertically formed. In this case, the goods supporting beam may be manufactured by downwardly raking a contact surface of the goods supporting beam 50 which comes in contact with the goods supported by the H-shaped structural steel member, that is, upper portions of both ends of the upper flange of the goods supporting beam 50.

By doing this, it is possible to prevent the goods from being damaged by forming the edges of the upper flange of the goods supporting beam 50 to be rounded.

That is, by forming the edges of the goods supporting beam 50 in a curved shape, it is possible to prevent the goods from being damaged when the goods supporting beam 50 comes in contact with the goods.

The goods supporting beam 50 may be an integral type that is fixed to the goods supporting post 40, or may be a detachable type that is detachably attached to the goods supporting post 40.

Here, the detachable goods supporting beam 50 may be attached or detached from a support bracket joined to the goods supporting post 40 by a bolt.

For example, since the plurality of goods supporting beams 50 to be joined to one goods supporting post 40 are integrally welded to the goods supporting post 40 as one unit, it is possible to install the goods supporting beams by simply assembling joined portions between the goods supporting beams 50 and the horizontal support beam 30 by bolts.

When wire rods that are just produced in a factory are layered, since the temperature of the goods is high, heat of the goods may be directly transferred to a structure main body.

In order to prevent this, support brackets to be joined to the goods supporting post 40 may be provided to a lower part of the goods supporting beam 50.

In addition, by assembling the detachable goods supporting beam 50 manufactured separately from the goods supporting post 40 to an upper part of the support bracket with a joining plate interposed there between by a bolt, it is possible to provide the goods supporting beam to the goods supporting post 40.

In this method of supporting the goods supporting beam 50, when the goods supporting beams 50 are integrally welded to both ends of the goods supporting post 40 to have an undeliverable size, by providing the support brackets at the both ends of the goods supporting post 40 to have a deliverable width, it is possible to apply the goods supporting beams to general goods.

In some cases, in the storage rack 100 of the present invention, the fixed goods supporting beams 50 and the detachable goods supporting beams 50 may be arranged together with.

For example, in the storage rack 100 of the present invention, the fixed goods supporting beams 50 and the detachable goods supporting beam 50 may be arranged together with at one goods supporting post 40.

Alternatively, in the present invention, only the fixed goods supporting beams 50 may be arranged at one goods supporting post 40, and only the detachable goods supporting beams 50 may be arranged at the other goods supporting post 40.

FIG. 10 is a perspective view showing an arrangement structure of the goods supporting posts and the horizontal support beams of FIG. 5.

As shown in FIG. 10, the storage rack 100 may include the plurality of lattice posts 10, the post connecting beams 20, the horizontal support beams 30, the plurality of goods supporting posts 40, and the plurality of goods supporting beams (not shown).

Here, the plurality of lattice posts 10 may be arranged in the X-axis direction at the second distance d2.

In this case, the lattice post 10 may include the post elements 11 and the vertical lattice member 12, and the post elements 11 may be arranged in the Y-axis direction at the first distance d1.

The vertical lattice member 12 may be connected between the post elements 11 in the form of zigzag in the Z-axis direction.

The post connecting beam 20 may connect one ends of the post elements 11 of the lattice post 10.

In some cases, the post connecting beam 20 may connect both ends of the post elements 11 of the lattice post 10.

The horizontal support beam 30 whose ends are fastened to the post connecting beam 20 may connect the lattice posts 10 arranged in the X-axis direction at the second distance.

Here, the horizontal support beam 30 that connects the lattice posts 10 may be one member.

The distance d11 between the one end of the horizontal support beam 30 and the post element 11 may be equal to the distance d12 between the other end of the horizontal support beam 30 and the post element 11.

The plurality of goods supporting posts 40 whose ends are fastened to the horizontal support beam 30 may be arranged between the lattice posts 10, which are arranged at the second distance d2, along the goods layering spaces at the forth distance d4.

Here, the ends of the goods supporting post 40 may be fastened to the horizontal support beam 30 to be overlapped therewith.

For example, the goods supporting post 40 may be completely overlapped with the horizontal support beam 30 in the Z-axis direction.

In this manner, when the goods supporting post 40 is overlapped with the horizontal support beam 30 on the plane, it is possible to increase structural stability and availability of the goods layering spaces.

In the storage rack of the present invention, the first distance between the post elements 11, the second distance between the lattice posts 10, the third distance between the goods supporting beams (not shown) and the fourth distance between the goods supporting posts 40 may be different from one another.

Here, these distances may be variously changed depending on the installation structure of the storage rack.

FIGS. 11 and 12 are side views showing a method of joining the horizontal support beam and the goods supporting post of FIG. 5.

As shown in FIGS. 11 and 12, the horizontal support beam 30 may be an H-shaped structural steel member that includes flanges 31 a and 31 b and a web 32 between the flanges 31 a and 31 b.

The goods supporting post 40 may be an H-shaped structural steel member that includes flanges 41 a and 41 b and a web 42 between the flanges 41 a and 41 b.

Here, a width W1 of the web 42 of the goods supporting post 40 may be equal to a width W2 of the web 32 of the horizontal support beam 30.

When the width W1 of the web 42 of the goods supporting post 40 is larger than the width W2 of the web 32 of the horizontal support beam 30, the goods layering spaces may be reduced. Accordingly, by using the member in which the width W1 of the web 42 of the goods supporting post 40 is substantially equal to the width W2 of the web 32 of the horizontal support beam 30, the flanges 41 a and 41 b of the goods supporting post 40 come in contact with the flanges 31 a and 31 b of the horizontal support beam 30, so that it is possible to ideally join the horizontal support beam and the goods supporting post as an integral structure.

A thickness T1 of the flanges 41 a and 41 b of the goods supporting post 40 may be equal to a thickness T2 of the flanges 31 a and 31 b of the horizontal support beam 30.

The flanges 41 a and 41 b of the goods supporting post 40 may be joined to the flanges 31 a and 31 b of the horizontal support 30.

As one example, the flanges 41 a and 41 b of the goods supporting post 40 and the flanges 31 a and 31 b of the horizontal support beam 30 may be joined through welding, but the present invention is not limited thereto.

As shown in FIG. 12, the horizontal support beam 30 may include a steel plate 33 that protrudes from the web 32 of the horizontal support beam 30 toward the goods supporting post 40.

Here, the steel plate 33 of the horizontal support beam 30 may be joined to the web 42 of the goods supporting post 40.

As one example, the steel plate 33 of the horizontal support beam 30 and the web 42 of the goods support beam 40 may be provided with at least one fastening hole 34, and may be joined by a bolt penetrating through the fastening holes 34.

FIGS. 13A and 13B are diagrams showing a method of joining the goods supporting beam and the goods supporting post of FIG. 5. FIG. 13A is a side view, and FIG. 13B is a front view of the goods supporting beam.

As shown in FIGS. 13A and 13B, ends of the plurality of goods supporting beams 50 may be fastened to the goods supporting post 40.

Here, edges of the upper flange 51 a of the goods supporting beam 50 that come in contact with the goods may be a curved shape.

FIG. 14 shows a front view and a cross-sectional view of the detachable goods supporting beam.

As shown in FIG. 14, the detachable goods supporting beam 50 may be attached to or detached from support brackets 51 joined to the goods supporting post 40 through bolts.

FIG. 15 is a front view showing a vertical brace and a connecting member of the storage rack according to the present invention.
